COP22 ended last week in high optimism that leaders will continue to invest in initiatives and actions that help avert the global warming crisis. This includes starting to review 'nationally determined contributions' this time by 2020 and investing in more renewable projects. Developing countries pledged to switch to 100 percent renewable energy by 2050 while developed countries reiterated their commitment to funding these initiatives.

Africa will need bold measures in order to avert a looming health and environmental crisis - which is the result of air pollution according to a recent OECD report. The report also shows that outdoor and indoor pollution in Africa are causing more death and carry more estimated costs than unsafe water and sanitation and childhood malnutrition. The report says that most of this pollution comes from energy generation, open fires in household operations and imported used equipment.

With solar power becoming a bankable alternative to fossil fuels, focus turns on how it can be made more cheaper, especially with large-scale power projects that hook to national grids. Scaling Solar wants to do that and is starting with two solar power plants in Zambia -- by helping companies, governments and financiers through the power agreement processes, financing, bidding, project management and contract-related issues.

Last month, South African Airways and Boeing celebrated flying the first-ever plane in Africa to be fuelled by biofuel from tobacacco. ProjectSolaris aims to produce local cleaner biofuel to power planes in South Africa, whilst providing local jobs. It means the aviation industry is also set and able to use biofuels, a measure that will help lower carbon-emissions. The South African Airways project will also produce biodiesel for cars and for other industries.

Another innovation with regard to solar energy category was that of solar roofing tiles presented by Strauss Energy. Strauss is into the business of incorporating solar cells - called Building Integrated Photovoltaic (BIPV) into building materials such as tiles. The solar tile is either made of a plastic material or mixture of plastic and ceramic components, with solar cells being overlayed on top. This model seeks to combine both the advantages of house roofing and power generation. The solar cells work in the normal way by converting sun’s energy into power which is then channeled to power devices at home, office or factory.
